Loxorhynchus grandis Stimp. 
A number of these large deep water forms come in every year. 
Fig. 18 is from Miss Ballard’s drawing of a fairly perfect specimen. 
L. crispatus Stimp. 
One specimen of this moss crab was dredged just off shore by 
Prof. A. M. Bean and W. F. Hamilton (Fig. 3). 
Cycloxanthops novemdentatus Lock, U.S.M. 
Fig. 2 of a small one. Fig. 1 larger. These rather large crabs 
with the dark tipped claws were sometimes taken inshore at low tide. 
Cancer antennarius Stimp. Fig 4. U.S.M. 
Found under the same conditions as the one just mentioned. 
Pilumnus spinohirsutus Lock. 
One poorly preserved specimen we took to be this species 
(Fig. 5). 
Heterocrypta occidentalis Dana 
Our specimen is from Hermosa Beach. Others have been re- 
ported from San Diego. We may yet find it at Laguna (Fig. 7). 
Pachygrapsus crassipes Randall 
The shore crab is found in great abundance on any rocky shore 
or in the nearer tide pools (Fig. 10). 
Lophopanopeus heathii Rath., U.S.M. 
The young of these were often found in masses of Polyzea under 
rock ledges. A young male was marked as follows: white claws with 
dark tips, last legs white, other legs and body dark red. A young 
female had red claws, hind legs white, body darker. Another young 
male was white. 
L. leucomanus Lock. 
Adults of these found under stones measured 14 mm. across. 
Young were found under rock ledges among alge and polyzoans. 
Young were found with red claws and a red mouth region. 
Dasygyius tuberculatus Lock., U.S.M. 
The hydroids on the Balboa piles were swarming with these pe- 
culiar spider-like crabs (Fig. 13).
